| Popis: |
The article presents a new method and a device for measuring the signal of thermoelectromotive force of a "tool – workpiece” natural thermocouple in the chip forming machining during the turning process. It is proposed to use a device of stationary current-collecting connection for fixing and measuring thermo-electromotive force signal, which allows to eliminate the influence of the transient resistance for existing constructions of movable current collectors. This circumstance makes it possible to reduce the measurement error of the signal and at the same time to increase its reliability. The review and analysis of the most similar constructive solutions have been carried out and there are also experimental data values which have been obtained when comparing the proposed device and the prototype. |
